PORTABLE ENGINE STAND.

Application filed October. 27, 1919.

To all whom it may concern:

Be it known that we, HARRY E. PATRICK, ANDREW J. PETERSON, and J OHN W. BERMES, citizens of the United States, residing at Evanston and Chicago, respectively, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Portable Engine Stands, of which the following is a specification.

Our invention relates to an apparatus suitable for use in connection with the assembling, disassembling or repair of internal combustion engines.

The invention in its broad aspect aims to provide an improved apparatus of the above character With which an internal combustion engine, or parts thereof, may be conveniently transported from one department to another of a shop during the course of the construction or repair of the engine, and which will present certain other advantageous features in connection with the application or removal of the engine from its operative position on a vehicle.

The invention more specifically contenp plates the provision of an improved apparatus of the above character which will be particularly suitable for use in connection with the construction or repair of farm tractor engines, particularly the engine used on the Ford tractor, or in other situations where the engine, instead of being supported on the vehicle frame, is, in effect, a part of the frame. When applying engines to vehicles of this type, it is necessary to accurately align the engine with the parts of the vehicle to which the en.- gine is fastened and maintain the engine in such alignment until it is firmly bolted in its operative position. It is also important to support the engine in alignment with the other portion of the vehicle body when disconnecting the engine from the body.

Prior to our invention various devices had been employed for supporting the engine, such, for example, as overhead hoists. These devices have not been entirely satisfactory for the reason that it is difiicult to effect the minute adjustment of the engine which is usually necessary when applying it to the vehicle. In other instances, particularly in smaller shops which are not provided with overhead hoists and where it is impractical or undesirable to run the tractor into the Serial No. 333,681.

Our invention aims to overcome the above and other difliculties in connection with the application of an engine to its operative position or its removal therefrom by providing a simple and inexpensive apparatus which is provided with means whereby the engine may be accurately adjusted when the same is being applied to the vehicle and which may be conveniently positioned under the engine so as to support the engine while it is being disconnected from the other parts of the vehicle, and in addition to the above features, to provide a truck which may be conveniently used to transport the engine t2 the desired departments of the repair s op.

The invention consists in the novel arrangements, constructions and combinations of parts hereinafter described and claimed for carrying out the above stated objects and such other objects as may appear from the following description of a preferred em bodiment of the invention.

In the drawings,

Fig. l is a view illustrating the manner in which the apparatus is positioned under the engine of a tractor, the tractor illustrated being of the Ford type and is shown in dotted lines in this figure.

Fig. 2 is a side view, in elevation, of the apparatus showing in dotted lines one of the side frames moved to its lower position so as to permit the apparatus to be readily positioned under the engine.

Fig. 3 is a vertical section taken through the apparatus on line 33 of Fig. 5.

Fig. 4: is a fragmentary view, partly in section, illustrating the manner in which the pivoted side frame of the apparatus is locked in its upright position.

Fig. 5 is a plan view of the apparatus, and

Fig. 6 is a side View of the same, the view being taken at right angles to Figs. 2 and 3, and certain devices being omitted for the purpose of clearness.

Like characters of reference designate like parts in the several figures of the drawings.

Referring to the drawings, 10 designates the base frame which is supported on casters 11. These casters are preferably provided with a ball bearing connection 12 (Fig. 2)

with the flanges 13 formed at the corners of the base 10. A rigid side frame 14 is secured at one edge of the base and preferably consists of corner posts 15 which may be bolted, as indicated at 16, or otherwise suitably secured to the base 10. The corner posts are connected and rigidified by means of cross braces 17, 17 which, are preferably formed integral with the corner posts. At the opposite edge of the base is a pivoted frame 18 which consists of corner posts 19 secured together by means of cross-pieces 20, 20 in substantially the same manner as described in connection with the frame 1d. The lower ends of-the corner posts 19 are bifurcated as indicated at 21 and fit over upstanding rigidifying ribs 22 formed on the base 10 and pivoted to said ribs by means of the pivoted pins 23. The lower end of each of these corner posts is also preferably provided with an angular extension 24 which is similarly bifurcated and provided with an aperture which when the frame is in its upstanding position registers with an aperture in the rigidifying rib 22. When the frame is in its upstanding position pin 25 may be inserted in said aperture so as to lock the frame in this position. The upper ends 26 of the corner posts 15, 19, are bifurcated as indicated at 27 so as to receive the dogs 28. lhese dogs are pivoted in the bifurcated portion, as indicated at 29,

and are formed at their inner ends with lugs 30 on whichthe flange A. of the engine crank case B is seated. The other end of these dogs are provided with forks 31 which extend around threaded studs 32 extending outwardly from the frames 1a, 18. Hand wheels 33 have threaded engagement with the studs 32 and are adapted to bear against the forked end of the dogs 28 so that by turning the hand wheels down on the studs the angular position of the dogs 28 may be changed so as to vary the position of the engine. Each of the dogs 28 may be separately adjusted and by this means a minute adjustment of the position of the engine may be accomplished.

Operation: When desiring to position the apparatus under an engine of a vehicle, a Ford tractor, for example, the frame 18 is lowered to the dotted line position shown in Fig. 2. While the frame is in this position the apparatus may be readily pushed under the engine and being provided with casters may be shifted to its proper position without difficulty. The pivoted frame 18' may then be raised to its upstanding position and locked in said position by means of the pin 25. By turning the hand wheels 33 down on the studs 32 the angular position of the dogs 28 are changed so as to bear against the under surfaces of the crank case flanges A. While the engine is thus supported it may be readily detached from the D. Before the bolts D are removed a suitable block E is placed under the transmis- I sion case so as to prevent it from dropping down. l/V hen the engine is supported on our apparatus the front wheels F and axle G may be readily removed and the engine, together with the radiator and other associated devices, moved into the shop for repairs, and as it is-passed through each department of the shop the device to be repaired in that department is removed and the engine passed on to the next department. After the engine has been repaired and reassembled it may be again attached to the transmission case C. In order to accomplish this it is usually necessary to effect minute adjustment so that the crank shaft of the engine will accurately align with the other operating mechanism ofthe tractor and so that the bolt holes of the engine and transmission case will register accurately.

This result may be accomplished by manipulating certain of the hand wheels 33 soas to move the engine to the desired position.

While we have described our invention in one preferred embodiment, it will be obvious that modifications might be made without mounted upon the base and the other move ably mounted thereon so as to raise and lower, whereby the stand can be moved un-' der the engine of a tractor until its rigid up right is against the side thereof and the movable upright can then be raised againstthe other side of the engine; and the two uprights being equipped for the seating be tween them of the object to be supported such as said engine, and provisions being made for securing the movable uprigh tin its raised position.
